When little police officer Lu Xin wakes up, he finds that he has transmigrated to the Middle Ages and become the second son of a count.
As an unfavored second son, Lu Xin faces two choices upon coming of age.
First, he can agree to become his half-brother's vassal, serve as the kennel master at his brother's castle, and manage all the hunting dogs.
Lu Xin: Heh. This future count wants the younger brother who's been at odds with him since childhood to be his kennel master. Is this an insult, or an insult?
Second, he can accept his count father's appointment as the steward of a village, responsible for managing its affairs, large and small.
Lu Xin: My dear old father, when a new emperor takes the throne, he appoints his own people. Once your eldest son inherits the title, won't he be able to do whatever he likes with me?
In the end, Lu Xin persuades his father to grant him a knight's fief that has been occupied by an impoverished foreign noble. After coming of age, he leaves the castle with the serfs and property he was given, determined to reclaim his fief.
The Count: Has this boy gone crazy? He thinks he can take back Tal Village with the eighty-odd serfs he got? That's laughable.
The Count's eldest son: It's just as well that this good little brother leaves with so little. That way, I won't have to kick him out myself later and look like a harsh lord.
Lu Xin: Hahaha! With the Taobao System in hand and an endless supply of goods, taking back a village will be a piece of cake.
The leader who occupied Tal Village, Williams, suddenly sneezed. He had a strange feeling something big was about to happen.
Premise: Hold on to hope and work hard to live.
